Description

Technical Field

[0001] This utility model relates to an ultra-high pressure water / gas testing device, and more particularly to an ultra-high pressure water / gas testing device. Background Technology

[0002] With the rapid development of aerospace, energy, petrochemical and other fields, ultra-high pressure water / gas testing is increasingly widely used in industrial production and scientific research. As an important tool for testing product performance and verifying design schemes, the accuracy, safety, and automation of ultra-high pressure water / gas testing equipment directly affect the reliability of test results and the safety of the testing process.

[0003] Currently, most traditional ultra-high pressure water / gas testing equipment is operated and monitored manually. This method not only requires professional technicians to be on-site for extended periods, but also makes it difficult to guarantee testing accuracy and consistency due to human factors. Furthermore, testing under ultra-high pressure environments poses significant safety risks, threatening the personal safety of testing personnel.

[0004] In the prior art, there are several improved solutions for electrical testing systems.

[0035] The valve drive module 32, data acquisition module 33, and continuity / insulation test module 34 are integrated onto three data acquisition cards. In this embodiment, the data acquisition cards used are a PCIe-4065-NI data acquisition card, a PXIe-4310-NI data acquisition card, and a PXIe-4310-NI data acquisition card. All three cards are inserted into the expansion slots of the CPCI measurement and control host chassis 3 and connected to the host interface 31 via an internal bus. These three acquisition cards also integrate a digital multimeter, enabling them to perform the functions of a digital multimeter.

[0036] The valve drive module 32 includes multiple DO signal output interfaces for controlling the on / off states of 24 valves on the tested object 6. The valve drive module 32 integrates a power amplifier circuit, providing sufficient drive capability to ensure reliable valve operation. The valve drive module 32 also features overcurrent and short-circuit protection functions, improving the system's safety and reliability.

[0037] The data acquisition module 33 includes a DO signal interface and an A / D signal interface. The DO signal interface is used to output control signals to control the operating status of various devices on the tested object 6. The A / D signal interface is used to acquire signals from various sensors on the tested object 6, including pressure sensors, temperature sensors, and flow sensors. The data acquisition module 33 integrates a high-precision A / D converter, enabling high-precision data acquisition. The current acquisition frequency of the data acquisition module 33 is greater than or equal to 10kHz. This high-speed acquisition capability allows the system to capture transient changes during the experiment, providing more detailed and accurate information for the analysis of experimental data.

[0038] The A / D converter in data acquisition module 33 uses 16-bit resolution, enabling high-precision data acquisition. The input range of the A / D converter can be set via software to adapt to the output signal range of different types of sensors, improving the system's adaptability and flexibility.

[0039] The continuity and insulation test module 34 includes a DO signal interface for controlling the continuity and insulation test equipment on the object under test 6. The continuity and insulation test module 34 integrates a dedicated test circuit capable of testing the continuity and insulation properties of the object under test 6.

[0040] Control line 7 includes test leads and signal leads. The test leads are used to connect the continuity and insulation test module 34 and the object under test 6, while the signal leads are used to connect the valve drive module 32, the data acquisition module 33, and the object under test 6. Control line 7 uses shielded cable, which effectively reduces the influence of external electromagnetic interference on the signal and improves the system's anti-interference capability.

[0041] The test object 6 is the equipment that needs to undergo ultra-high pressure water / gas testing, and can be various types of pressure vessels, piping systems, valves, etc. Various sensors are installed on the test object 6 to monitor various parameters during the test, such as pressure, temperature, and flow rate. Various valves are also installed on the test object 6 to control the fluid flow during the test.

[0042] The remote monitoring unit 2 is a standalone device, which can be a computer, a tablet, or a smartphone. It transmits data wirelessly to the CPCI measurement and control host chassis 3 to achieve remote monitoring of the testing process. The remote monitoring unit 2 runs dedicated monitoring software that can display various parameters during the testing process in real time and remotely control the testing process.

[0043] The local testing unit 1 also includes an HMI local monitoring display screen 4, which is connected to the CPCI measurement and control host chassis 3 via an HDMI cable. The HMI local monitoring display screen 4 can acquire data from the tested object 6 collected by the CPCI measurement and control host chassis 3 in real time via the HDMI cable. The HMI local monitoring display screen 4 runs dedicated monitoring software, which has the same functions and interface as the monitoring software on the remote monitoring unit 2. It can display various parameters during the test process in real time, including pressure, temperature, flow rate, and the results of continuity and insulation tests. These parameters are displayed intuitively in the form of graphs and curves, facilitating viewing and analysis by on-site operators.

[0044] Local test unit 1 is connected to the MQTT gateway 5 via a network cable and based on the Modbus protocol. The MQTT gateway 5 has a built-in 4G wireless communication module and communicates with the remote monitoring unit 2 through the 4G wireless communication module.

[0045] The working process of the ultra-high pressure water / gas testing equipment in this embodiment is as follows:

[0046] First, the operator sets the test parameters, including test pressure, test time, and data acquisition frequency, through the CPCI control unit 3 in the local test unit 1 or the remote monitoring unit 2. These parameters are then transmitted wirelessly to the host interface 31 of the CPCI control unit 3.

[0047] Then, the host interface 31 controls the valve drive module 32 to output corresponding control signals according to the set parameters, and controls the valve on the object under test 6 through the control line 7 to adjust the flow of fluid so that the pressure inside the object under test 6 reaches the set value.

[0048] Next, the data acquisition module 33 acquires signals from various sensors on the object under test 6 via control line 7, including signals from pressure sensors, temperature sensors, flow sensors, etc. These signals are converted into digital signals by the A / D converter of the data acquisition module 33, and then transmitted to the host interface 31 via the internal bus.

[0049] The host interface 31 processes and analyzes the collected data, and then transmits the processed data to the HMI local monitoring display screen 4 and the remote monitoring unit 2 via HDMI cable and wireless connection, respectively, for operators to view and analyze.

[0050] Meanwhile, the continuity and insulation test module 34 performs continuity and insulation tests on the test object 6 through the control line 7. The test results are transmitted to the host interface 31 through the internal bus, and then transmitted to the remote monitoring unit 2 through a wireless connection.

[0051] Throughout the test, operators can monitor the test status in real time through the HMI local monitoring display 4 and the remote monitoring unit 2, including changes in parameters such as pressure, temperature, and flow rate, as well as the results of continuity and insulation tests. If any abnormality is detected, operators can issue control commands through the HMI local monitoring display 4 or the remote monitoring unit 2 to stop the test using the CPCI measurement and control host box 3, ensuring the safe conduct of the test.

[0052] After the test, the host interface 31 saves the data of the entire test process to the internal memory and transmits it to the remote monitoring unit 2 via wireless connection for subsequent analysis and processing by the operator.

[0053] In this embodiment, the valve drive module 32 and the data acquisition module can also be used to test the solenoid valve's operating characteristics. The specific process includes:

[0054] Operators set test parameters through the CPCI control host box 3 in the local test unit 1 or the remote monitoring unit 2. The parameters are transmitted to the host interface 31 of the CPCI control host box 3 via wireless connection.

[0055] According to the set parameters, the host interface 31 controls the valve drive module 32 to output corresponding control signals, and controls the solenoid valve on the object under test 6 through the control line 7. Single valve control is adopted. The solenoid valve under test continuously performs opening and closing actions. The action time width of each valve is required to be 80ms, the time interval between two actions is 40ms, and the time interval between the actions of two adjacent solenoid valves is 200ms.

[0056] Data acquisition module 33 acquires the transient current of the solenoid valve on the object under test 6 through control line 7, and generates... Figure 2 The characteristic curves are shown. During testing, the start-up time t1, start-up current I1, release time t2, release current I2, and steady-state current I should be recorded, and the ratios of start-up current to steady-state current (I1 / I) and release current to steady-state current (I2 / I) should be calculated. The solenoid valve's operating characteristics can be obtained through... Figure 2 The relationship between the current value of the solenoid valve coil in the aerospace propulsion system and time is shown.

[0057] Example 2

[0058] Based on embodiment 1, the DO signal interface of the data acquisition module 33 includes a remote shutdown signal interface 331, which is connected to the object under test 6 via control line 7.

[0059] The remote shutdown signal interface 331 is a dedicated DO signal interface used to quickly close all valves on the test object 6 in an emergency, stopping the test. The remote shutdown signal interface 331 is directly connected to the emergency shutdown system on the test object 6. When a shutdown signal is received, the emergency shutdown system will immediately close all valves, releasing the pressure inside the test object 6 and ensuring the safety of the test.

[0060] The remote shutdown signal interface 331 adopts a redundant design, including two independent signal channels, each of which can independently control the emergency shutdown system on the tested object 6. This redundancy design improves the reliability of the system; even if one signal channel fails, the other signal channel can still operate normally, ensuring the reliable implementation of the emergency shutdown function.

[0061] The remote shutdown signal interface 331 also has a self-diagnostic function, which can monitor the status of the signal channel in real time. If a fault is detected in the signal channel, it will immediately report to the host interface 31. The host interface 31 will transmit the fault information to the remote monitoring unit 2 through a wireless connection to remind the operator to handle it in time.

[0062] In addition, the data acquisition module 33 also has an automatic emergency shutdown function. When the pressure, temperature and other parameters acquired by the data acquisition module 33 through the A / D signal interface exceed the preset safety threshold, the emergency shutdown function will be automatically triggered. The shutdown signal will be output through the remote shutdown signal interface 331 to control the emergency shutdown system on the tested object 6, close all valves, stop the test, and ensure the safety of the test.

The information receiving device connects to the ultra-high pressure water / gas testing equipment wirelessly to achieve real-time information transmission.

[0066] When the mobile phone is used as an information receiving device, a dedicated monitoring app can be installed to receive and display information sent by the ultra-high pressure water / gas testing equipment.
